R aymond Davis Jr., a BNL re- tired chemist, has won the 2002 Nobel Prize in Physics for detecting solar neutrinos, ghost- like particles produced in the nuclear reactions that power the sun. As announced on October 8, Davis shares the prize with Masatoshi Koshiba, Japan, and Riccardo Giacconi, U.S. In awarding the prize to Davis and Koshiba, the Royal Swedish Academy of Sciences cited both “for pioneering con- tributions to astrophysics, in particular for the detection of cosmic neutrinos.” Giacconi was cited “for pioneering con- tributions to astrophysics, which have led to the discov- ery of cosmic x-ray sources.” Said Davis, “I was very sur- prised by the news that I had received the Nobel Prize. I had a lot of fun doing the work. I could never have done it with- out the aid of colleagues all over the world, especially at BNL, the Homestake Mine, and the Uni- versity of Pennsylvania.” The Nobel laureates will be awarded their prizes at a cer- emony in Stockholm, Sweden, on December 10. The prize con- sists of a diploma, a medal, and 10 million Swedish kroner (roughly 1 million U.S. dollars) shared among the recipients. “Neutrinos are fascinating particles, so tiny and fast that they can pass straight through everything, even Earth itself, without even slowing down,” said Davis. “When I began my work, I was intrigued by the idea of learning something new. The interesting thing about new ex- periments is that you never know what the answer is going to be.” Davis was the first scientist to detect solar neutrinos, the signature of nuclear fusion re- actions occurring in the core of the sun, using a method to de- tect solar neutrinos based on the theory that the elusive particles produce radioactive argon when they interact with a chlorine nucleus. To protect it from cos- mic rays, Davis’s first solar neu- trino detector was constructed 2,300 feet below ground in a limestone mine in Ohio (see photo, page 2), in 1961. Build- ing on this experience, he mounted a full-scale experi- ment 4,800 feet underground, in the Homestake Gold Mine in South Dakota. In research that spanned 1967-1985, Davis consistently found only one-third of the neutrinos that standard theories predicted. His results threw the field of astrophysics into an uproar, and, for nearly three decades, physicists tried to re- solve what is called the “solar neutrino puzzle.” Experiments in the 1990s using different detectors around the world eventually confirmed the solar neutrino discrepancy. Davis’s lower-than-expected neutrino detection rate is now accepted by the international science community as evidence that neutrinos can change from one of the three known neu- trino forms into another. This characteristic, called neutrino oscillation, implies that the neutrino has mass, a property that is not included in the current Standard Model of elementary particles (in contrast, particles of light, called photons, have zero mass). Davis’s detector was sensitive to only one form of the neutrino, so he observed fewer than the expected num- ber of solar neutrinos. Raymond Davis Jr. earned a B.S. and an M.S. from the Uni- versity of Maryland in 1937 and 1940, respectively, and a Ph.D. in physical chemistry from Yale University in 1942. After his 1942-1946 service in the U.S. Army Air Force and two years at Monsanto Chemical Company, he joined BNL’s Chemistry De- partment in 1948. He received tenure in 1956 and was named senior chemist in 1964. From 1971 to 73, Davis was a member of the National Aero- nautics & Space Adminis- tration’s Lunar Sample Review Board and was involved in the analysis of lunar dust and rocks collected by the crew of Apollo 11 on NASA’s historic first flight to the moon. Davis retired from BNL in 1984, but has an appointment in the Chemistry Department as a research collaborator. In 1985, he joined the University of Pennsylvania (UP) to continue experiments at the Homestake Gold Mine with Kenneth Lande. Davis has an affiliation with UP as a research professor emeritus. A member of the National Academy of Sciences and the American Academy of Arts and Sciences, Davis has won numer- ous scientific awards, including the 1978 Cyrus B.

Over the past few years, sci-entists have developed

new materials for informationstorage applications, often inthe form of thin-layered films.

The technology has evolvedto the point where individuallayers may be only a few na-nometers — literally just tens ofatoms thick. Such multilayeredstructures not only promise togo beyond the limits of thememory density of currentcomputers, but also display avariety of complex magneticproperties that scientists areonly beginning to understand.

For example, scientists can as-semble many layers of ultra-thinfilms, creating structures withelectrical properties that can dra-matically change depending onthe values of an applied magneticfield, a phenomenon called giantmagnetoresistance. Another puz-zling property is the co-existence,in some ultra-thin magnetic filmscalled half-metallics, of both me-tallic and insulating properties.

Gerhart FriedlanderBNL retiree, Chemistry Depart-ment Chair, 1968-77

Much credit for launchingthe Homestake experiment be-longs to Richard Dodson, chairof the Chemistry Departmentwhen Ray proposed the experi-ment. From the outset, Dodsonhad given Ray a free hand topursue his scientific interests— that was his managementstyle — and so it was naturalthat Dodson gave the solarneutrino project his whole-hearted support.

Also crucial was the fundingprovided by Alexander VanDyken of the AEC [Atomic En-ergy Commission], who coura-geously supported the project ata time when it was not gener-ally thought to promise success.

Dodson sent Morris Perlmanand me — both chemists — tothe mine in 1967 to checkthings out. That’s because whenRay started to get his first re-sults, they indicated a problem— too few neutrinos. Dodsonthought we’d better have someindependent judgment. Wefound that everything was fine.

People through the years sug-gested many alternate explana-tions for Ray’s data, but hepainstakingly disproved themone by one until he was, aftermany years, able to convincemost of the doubters that hewas correct. His results haveabsolutely stood up for the past30 years. Through that time,

Solar Neutrino Experiments

Neutrinos are ghostlike particles that were postulated byWolfgang Pauli in 1930 on purely theoretical grounds and,

until recently, were believed to have zero mass. Solar neutrinosare thought to be produced in the nuclear reactions that providethe sun’s energy. They rain down on each square inch of the Earthat the rate of about 400 billion per second.

In the 1950s, Raymond Davis Jr. started investigating neutri-nos that were produced in Brookhaven’s Graphite Research Reac-tor and at a reactor at the Savannah River Plant in South Carolina.But these experiments were really the prelude to Davis’s majortriumph, which came in the early 1970s, when he successfullydetected solar neutrinos in a new experiment based in Lead, SouthDakota.

A solar neutrino was expected to produce radioactive argonwhen it interacted with a nucleus of chlorine. Davis developed anexperiment based on this idea by placing a 100,000-gallon tank ofperchloroethylene, a commonly used dry-cleaning chemical anda good source of chlorine, 4,800 feet underground in the Home-stake Gold Mine in South Dakota and developing techniques forquantitatively extracting a few atoms of argon from the tank.

The chlorine target was located deep underground to protect itfrom cosmic rays. Also, the target had to be big because the prob-ability of chlorine’s capturing a neutrino was ten quadrillion timessmaller than its capturing a neutron in a nuclear reactor. Despitethese odds, Davis’s experiment confirmed that the sun producesneutrinos. But only about one-third of the number of neutrinospredicted by theory could be detected.

This “solar neutrino puzzle” gave birth to different experimentsby scientists around the world, all working to confirm the solarneutrino deficit. First came Kamiokande in Japan, then SAGE inthe former Soviet Union, GALLEX in Italy, and then SuperKamiokande. Finally, in 2001-2002, scientists working at SNO, theSudbury Neutrino Observatory in Ontario, Canada, found strongevidence that the neutrino has the ability to oscillate, or changeform, among its three known types: the electron, muon and tauneutrinos.

In those days, everything wasfun at the Lab. People did theirwork, they enjoyed it, theyloved it.

The Goldhabers were alwaysinterested in the experiment.Whenever Maurice [Brook-haven Director, 1961-73] sawme on the street, he would al-ways ask about the mine.Gertrude said that it would be alot more exciting if you didn’thave what they predicted. Andthat was the gist of it.

J. Keith RowleyBNL retiree, Chemist in the Chem-istry Department, 1953-99

I made 25 trips to Home-stake, staying one or two weeksat a time. The local folks, espe-cially the miners, all knew usbecause of the publicity sur-rounding the experiment. Theirstandard greeting was, “Catchany today?”

It was about 90 degrees [Fahr-enheit] underground. Remem-ber that the center of the Earthis molten, so it’s hotter as you

Chemistry Retirees Reminisce About Ray Davismajor scientific collaboratorswere Don Harmer, John Evans,Dutch Stoenner, Keith Rowley,Bruce Cleveland and, of course,John Bahcall on the theory side.

It was all an heroic chemis-try experiment. Fishing out afew atoms of argon from a hun-dred thousand gallons of per-chloroethylene is the ultimateradiochemical experiment. It’s akind of job only chemists cando. And not many chemistswould have had Ray’s persis-tence to do it.

N. Blair MunhofenBNL retiree, Chemistry Depart-ment Administrator, 1953-90

I was more in the business ofgetting things done, installed,etc. It took some time to con-struct the experiment. You hadall the parts to order and puttogether. It was a big operation.

One of the problems that hadto be solved was how do youthoroughly mix the heliumwith the perchloroethylene. Wehad help from people on site innuclear engineering, who cameup with the use of educters. Rayand I had never heard of such athing. We wanted to test thisout, so, at Brookhaven, we hada ten-foot diameter Plexiglasring built, which we placed inthe Lab swimming pool. Ray,John Galvin, and I had to getcertified to use scuba gear to testthe eductors under water.[Munhofen is shown duringthese tests in the photo at right.]

go deeper. Usually, we wentdown before 7 in the morningand left by 9:30 at night. Wehad to get out before the lastrestaurant closed. All meals weresocial occasions, and there wasa lot of discussion about whathad been done, what we weregoing to do, and gossip in thesolar neutrino field.

The space outside the detec-tor was filled with water, to slowdown any neutrons comingfrom the rock walls of the cham-ber. These neutrons could leadto a series of reactions thatcould produce argon, whichwould increase the signal. So itwould be a higher signal, but afalse signal. The water was cer-tainly warm enough to swim in,but I never did.

Ray was very generous, al-ways offering his help. Peoplecame to him asking for space inthe mine to do their experi-ments. That’s how Ken Landefrom Penn came to set up hiscounters in the mine, althoughsome of the other experiments

were not even relatedto neutrinos. Ray al-ways bent over back-wards to help people.

Early on, we’dbrought back samplesto BNL for counting,hand-carrying themin glass containersthrough airport secu-rity. You probablycouldn’t do that to-day. — Mona S. Rowe

The Daedalus String Quartet, 10/16

The Daedalus Quartet, an exciting new string quartetformed in the summer of 2000 by participants at theMarlboro Music Festival, will present a noon recital onWednesday, October 16, in Berkner Hall.

The Quartet is quickly making a name for itself in thechamber music world. The group has performed in recitalsin New Jersey, on Long Island, and at Columbia University,and has been coached by such renowned pedagogues asDonald Weilerstein and Peter Salaff. Members of the DaedalusQuartet have studied at the Juilliard School, the Curtis Insti-tute of Music, Harvard University, and the Cleveland Insti-tute of Music. In addition to the Marlboro Festival and Mu-sicians from Marlboro tours, the members have participatedat the Taos, Aspen, Banff, and Angel Fire Festivals.

Following their performance at BNL in August last year,the quartet traveled to the Banff Centre to participate in theInternational String Quartet Competition, where they wereawarded first prize.

Noon recitals are free and open to the public. Bring yourlunch, and come and go as you please.

Hospitality Committee

Cruise News The rain held off on August

28, and 90-plus cruising enthu-siasts from the Lab, sponsoredby the Hospitality Committee,set sail with other passengers onthe Port Jefferson ferry’s “Sun-set Cruise to Nowhere.”

Gusty winds blew chairsabout the deck, but the rollick-ing singalong led by Banjo Boband Crazy Henry lured manycruisers to brave the weatherand eat their picnic suppers out-side. As the ferry left Bridgeportto return to Port Jeff, a pinkglimpse of the advertised sun-set emerged through the clouds.

The Hospitality Committeehopes that even more membersof the Lab community will jointheir next ferry trip, in August2003. No guarantees on the sun-set, but the 2002 cruisers agreethat the great time and pricewould be hard to beat.
